Impacted canines that are malpositioned, but have a favourable root pattern (without hooks or sharp curves) may be considered for autotransplantation into the dental arch. Vermette ME, Kokich VG, Kennedy DB. The risk of damaging adjacent teeth is also higher with teeth in an intermediate position. - Patients older than 12 years of age and with non-palpable canines and/or canines in sector 4 or 5, as well as, if space defficiency exists in the Chaushu et al postulated that if the ratio of the canine to the central incisor is greater than or equal to 1.15, the canine is likely palatally positioned.11 Third option is to look for canine superimposition on the root of the central incisor, as proposed by Wolf and Mattila.12 As per their rule, if impacted maxillary canine is superimposed . A flap is first elevated over the area of the impacted tooth. vary according to clinical judgment and experience. Canines in sector 1 and 2 had significantly Premolars, incisors and other teeth may be impacted but most of the surgical principles and approaches mentioned for canine can be applied to them as well. Another alternative technique is to use a crevicular incision, expose palatally and place orthodontic brackets as shown in Fig. Class II: Impacted canines located on the labial surface. surgical and orthodontic techniques for the proper management of impacted maxillary 15.7c, d).

Cantilever mechanics for treatment of impacted canines. For cases that are deeply impacted, triangular flaps (2sided) or trapezoidal flaps (3 sided) may be used, with incisions along the gingival margin and relieving incisions. A different age has different trees, which should be followed accordingly. recommended to be taken when it will make a change in the treatment plan. Kuftinec [12, 13] asserts that if the canines cusp is mesially at the root of the lateral incisor, the impaction is probably palatal but if the cuspid is found overlapping the distal half, a labial impaction is more probable. The upper cuspid: its development and impaction. T wo periapical films are tak en of the same area, with the . Crown in intimate relation with incisors. Closed eruption technique: If the impacted canine lies in the middle of the alveolus, near the nasal spine, or high in the buccal vestibule or the palate, this technique may be indicated (Vermette et al., 1995) [19]. If there is haemorrhage, it can usually be controlled by pressure application. The mucoperiosteal flap is then reflected to reveal the palatal bone and the tooth.
